. Be it known that I, TAYLOR E. vDANIELS, a citizen of the UnitedStates, residing at Ohicago, in the county of Cook and State ofIllinoie, have invented a new and useful Improvement inExcavating-Machines, of which the following is aspecification.

. 'My present invention is in the nature of an improvement'on theexcavating-machine described in my pending application, Serial No.102,819, filed April 14, 1902. c

I My primary object is to provide-a machine of this characterparticularly adapted. to the purpose of producing holes or horesofconsiderable depth.

The invention is illustrated in its referred embodiment in theaccompanying d "ings, in which- 4 is,

3o lever through the medium of which the clutch member K4 is shifted; L,a gear at the upper end of the shaft K5', meshing with a pinion L on oneend of a shaft journaled in a bearing L2 on the top :frame member. A2;and L3, a

3 5 pinion on the opposite end of said last-named screws b, extendinginto an annular channel in the sleeve extension of said gea-r. The slidc B is of the form shown in Fig. 3i, having per forate Vertical bossesb' for receiving the frame members A; divided journal-boxes b2 5o forreceiving the pinions E' E2 ou the shaft E; a hood b3, with which thethreaded rod B' is connected and which serves to house the rotary brushDn; bearings b* b5 for the sleeve l)3 and one end of the shaft D, saidbearings 5 5 being` separated by a space b, which receives thesprocket-wheels l)' D2, and brackets IF b, which support the shaft D".Attached to the slide B is a shield b, over which the dirt and materialsbrought up by the cutter-chains 6o are swept by the rotary brush.

The member B3 has dovetailed connection with thc extension B2 of theslide B and is firmly bolted to said extension, as illustrated in Fig.14. The member l* has dovetailed connection with said extension B2 andis adjust-ably secured thereto by bolts c, Fig. 1, passing through slotsc' in said extension.

`'.lhe member l",l"ig.'i0, is connected with the member B3 by a threadedshaft d. The

upper portion of said shafthas threaded connection with the memberjl,and the lower end thereof is. journaled lin. thc member li and confinedagainst longitudinalmovement with relation thereto. 'l`le1\ lowerextremity vof said shaft is equipped with a bevel-pinion d', whichmeshes with a pinion 1F von a transverse shaft d, suit-ably journalcd inthe niember Il* and having,r a squaredprojecting end 1.4, whichfreceives a crank d, Fig. G, through the medium of which, the member lmay be raised or lowered with relation to the inember li after firstloosening the bolts c.

The casing,r C comprises an uppersection f, a lower section f', andinterchangeable intermediate sections f2. The upper section is suitablyconnected at its upper end with the member B, and preferably is readilydetachable therefrom. 'lhc lower end of the lower section supports theshaft of the sprocketwheels C304. Each section of thecafsing,r preferably comprises channel-bars y g', Fig. 7, having tbeirianges turnedtoward each other, strips or bars g2, connected with the flanges of thechannel-bars, and sheet-metal members g3, bent to .form angles, asshown. The mem bers q2 and .fianges of the channel-bars are ou tersurfaces of the webs of the channel-bars are equipped with guidefgroovesfor receiving, plates h, Figs. 7 and 8, eonnectcd with cutter-chains.The chains are guided 'and caused to produce avehannelof slightly-greater cross-section than the casing C by means of the structuredescribedhercin'and claimed in the above-mentioned application.

lThe preferred manner of connecting the casing-sections is illustratedin Figs. 1l and secured together byanysuitablemeans. 'lhe x oov 12,where the upper ends of the membersg2 are shown to project above theupper end of the casing-section, while the lower ends of said membersstop short of thc lower end of the section. The lower ends of the casingmembers g3 and the upper ends of the members gj2 are provided withrefistcring pcrorations, through which pass bolts j. I have shown thechannel-bars provided with dewelpins also, but these mayA bcdispcnscdwith. The casing C extends freely thmugh aguideopening in the mainportion of the base A of the main frame, as shown in Fig. 6.

The construct-ion of the levers .l2 .i3 is illustrated in Figs. 4 und'lhus the lever.)2 is pivot-od at a point l. and has a downwardlyextendingvr arm k', bearinga pin ki, upon which rests one end of a leverla, pivot ed at its ccntral portion at k. Euch end of the level' k isprovided with a V-shaped notch k", which receives the pin ki when thelever is in the central position. When either of the levers J2 or J3 isthrown to a position to shift its clutch into engagement with one of theadju# cent gears,the corres poudin gpoint k2 is fo reed along;` one ofthe inclines ofthe V-shaped notch thereat and' produces a pressure uponthe lever, whichserves to lock the other lever against movement. This isa safety feature providing against throwing two sets of gears l ofdifferent speed Vinto operation at the sametime.

The lever KW is pivoted has an arm projecting downwardly below saidpoint and rovided with a pin l'.

The pin mayenter any one of the three perforations I?. (Shown in Eigl'.)When the pin is in the central one of these perforations, the clutchmember K* occupies a central po sition and does not engage with eitherof the pinions Kz K.

The operation will be understood 'readily' the levers J* J 5 in onedirection or the other,'

according tothe speed desired. When this is done, power is transmittedfrom the shaft F to the shaft G, and lthence to the shaft E.

and the shaft K. The shaftE operates the cutter chains through themedium of the pinions D D5. The leverK10 may be shifted vfrom itscentral position intoengagement with the proper one of the pinions if2Ks to cause the screw B' to be fed downwardly, and this may be doneeither before starting the cutter-chains or after.. After the slide Bhas reached the lower end of its traverse the levers in use may beshifted. to their central positions to stop the cutting and feedingoperations. The casings andcutter-chains may be separated at theuppermost joint of the casing and a new section of chains and a newsection of casing inserted after first raising the slide B to the upperend of lits guides.

In most soils it is advantageous to introduce a pipe into the hole as itis beingmade. Such a pipe may be built up., of sections as the work ofexcavation proceeds, the pipe occu'pying the position indicatedV bythedotted lines M in Fig. 7. This is of particular advantage where it isnecessary to employ a pump to elevate the fluid entering the pipe. Thefeature of carrying the casing down with the cutter-chains preventscaving in of the soil and renders it possible to extend the bore throughsoils where ordinary well-d rillin g ma chines would not suce.

. The operation of a machine of the sam general character is describedin the abovementioned application, and it is only necessary to add thatthe brush D1l servestoremove the materials from the cutter-chains as thecutters and buckets of the chain pass successively beneath it. Thebrushis preferably provided with steel bristles.

Changes in details of construction within at a point l and -slidablyconnected with said vertical shaft the spirit of my invention may bemade. Hence no undue limitation should be understood from the foregoingdetailed description.
